Objective Venous thromboembolism (VTE) still remains a significant public health problem due to gaps between recommendations and clinical practice in VTE prophylaxis. This is the first clinical study designed to evaluate the applicability of a standard ‘VTE prophylaxis and risk factor assessment form (VTE-PRAF)’ and prescription of VTE prophylaxis among hospitalized patients in the daily practice of general surgeons in Turkey. Method A total of 1472 patients (mean age: 52.4 ± 16.9 years; 50.6% were men) were included in cross-sectional ( n = 537), first longitudinal ( n = 452) or the second longitudinal ( n = 483) phases. Data on demographics, hospitalization, surgical intervention and prophylaxis were collected during the cross-sectional phase, whereas utilization of form was evaluated during longitudinal phases. Results While 62.1% of patients were identified to be at ‘high+ highest’ risk, prophylaxis was evident only for 65.9%. Utilization of the form was higher in the second longitudinal phase ( P < 0.001) but there was no relation between implementation of the form and prophylaxis use. VTE-PRAF was completed for 70.6% and 84.8% of patient who received prophylaxis while it was completed for 50.8% and 50.4% of patients with no prophylaxis, in the first and second longitudinal phases, respectively. Prophylaxis was administered in 58.6% and 62.6% of patients with completed VTE-PRAF in the first and second longitudinal phases, respectively. ‘Suggested’ and ‘used’ prophylaxis regimens were significantly more consistent for the cases evaluated with VTE-PRAF ( P < 0.001). Conclusion Based on the use of prophylaxis only for 65.9% of general surgery inpatients at high risk for VTE, low use of prophylaxis is assumed to remain a significant threat to public health across Turkey. Inclusion of a standard VTE-PRAF in the hospital protocol seems to raise clinical awareness of VTE risk assessment and appropriate management in VTE which otherwise well-known to be associated with significant mortality and morbidity. Impact of e-VTE-PRAF is worth investigating.

Objective To determine the incidence of postoperative venous thromboembolism (VTE) in adults undergoing otologic surgery. Study Design Cross-sectional retrospective study. Setting Single tertiary academic center. Subjects and Methods Adults undergoing nononcologic, extracranial otologic surgery from August 2009 to December 2016. Patients with postoperative diagnosis VTE codes were identified. Imaging and clinical documents were searched for VTE evidence within the first 30 postoperative days. Methods of thromboprophylaxis were documented, and Caprini risk scores were calculated. Results In total, 1213 otologic surgeries were evaluated. No postoperative VTE events were identified (0/1268). Mean age was 51.0 ± 17.3 years (range, 18.1-93.4 years). Average length of surgery was 136.0 ± 79.0 minutes (range, 5-768 minutes). The average Caprini score in all patients was 4.0 ± 1.7 (range, 1-15). Eighty-five percent of patients had a Caprini score ≥3, the threshold at which chemoprophylaxis has been recommended in general surgery patients by the American College of Chest Physicians 2012 guidelines. Six patients had documented preoperative chemoprophylaxis and a Caprini score of 4.8 ± 1.7. This was not significantly different from that of patients who did not receive preoperative chemoprophylaxis ( t test, P = .3). The literature would estimate a rate of 3.7% VTE in adults with similar Caprini scores undergoing general surgery procedures with no VTE prophylaxis. Conclusion The Caprini risk assessment model may overestimate VTE risk in patients undergoing extracranial otologic surgery. Postoperative VTE following otologic surgery is rare, even in patients traditionally considered moderate or high risk. Chemoprophylaxis guidelines in this group should be balanced against the potential risk of increased intraoperative bleeding and its associated effects on surgical visualization and morbidity.

Abstract Background There is a growing body of evidence showing substantial underuse of appropriate venous thromboembolism (VTE) prophylaxis in patients at risk. In the present study, our goal was to assess the current practices in the use rate of VTE prophylaxis among hospitalized patients in Jordan and Lebanon. Methods A cross-sectional, multicenter, observational study was conducted on 40 centers across Lebanon and Jordan. We included patients who were admitted to the participating hospitals for the treatment of a serious medical or surgical illness. The patients’ records were screened for the fulfillment of inclusion/exclusion criteria during a single assessment visit. The proportion of medical and surgical patients who were at risk of VTE and the thrombo-prophylactic measures employed by physicians for these patients were assessed according to the American College of Chest Physicians (ACCP 2016) guidelines. Results The present study included 704 patients (400 from Jordan and 304 from Lebanon) with a mean age of 54.9 ± 17.5 years. Almost 59% of the patients received prophylaxis treatment in form of pharmacological anticoagulant prophylaxis and/or mechanical prophylaxis. Low molecular weight heparin was the most commonly used anticoagulant for VTE prophylaxis in 366 out of the total 704 (51.9%) patients in the analysis cohort. Two hundred and sixteen patients (52, 95% confidence interval [47.1–56.9%]) received appropriate prophylactic agents out of 415 patients who were eligible for prophylaxis according to the ACCP 2016 guidelines. On the other hand, 199 (72.1, 95% confidence interval [66.4–77.3%) patients received prophylaxis out of 276 ineligible patients. The rate of compliance to guidelines showed wide variations according to the type of hospital, specialty, and the patients’ age. The multivariate logistic regression analysis showed that only age was a significant predictor of appropriate VTE prophylaxis (odds ratio [OR] 1.05, P < 0.001). Conclusion The rates of the appropriate use of VTE prophylaxis are low in Lebanon and Jordan. There is a lack of compliance to guidelines for VTE prophylaxis use for hospitalized patients in both countries.

Aims and methodWe assessed venous thromboembolism (VTE) risk, barriers to prescribing VTE prophylaxis and completion of VTE risk assessment in psychiatric in-patients. This was a cross-sectional study conducted across three centres. We used the UK Department of Health VTE risk assessment tool which had been adapted for psychiatric patients.ResultsOf the 470 patients assessed, 144 (30.6%) were at increased risk of VTE. Patients on old age wards were more likely to be at increased risk than those on general adult wards (odds ratio = 2.26, 95% CI 1.51–3.37). Of those at higher risk of VTE, auditors recorded concerns about prescribing prophylaxis in 70 patients (14.9%). Only 20 (4.3%) patients had a completed risk assessment.Clinical implicationsMental health in-patients are likely to be at increased risk of VTE. VTE risk assessment is not currently embedded in psychiatric in-patient care. There is a need for guidance specific to this population.

Abstract Aims Venous thromboembolism (VTE) is the leading cause of preventable hospital deaths; with hospital-acquired VTEs accounting for 50% to 60% of all VTEs seen. This project aims to review and improve the number of VTE risk assessments completed for surgical in-patients. Methods This retrospective, cross-sectional study involved data collection from surgical in-patients (n = 648) over three consecutive months, using an electronic VTE risk assessment tool. Data was categorised into ‘First VTE prophylaxis risk assessment completed within 24 hours of admission’ and ‘Second VTE prophylaxis risk assessment completed within 48 hours of admission’. This was further sub-categorised into surgical specialties. Results were presented in departmental meetings and educational posters were displayed. The study was re-audited using the same method over one month (n = 216). Results Results demonstrated improvement from the initial audit cycle, particularly in relation to the mean number of VTE risk assessments completed for patients undergoing breast surgery (100% from 95.3%), colorectal surgery (93.3% from 90%) and general surgery (88.0% from 86.6%). The mean number of first VTE risk assessments completed in 24 hours across all surgical wards remained above 65%, whilst the mean number of second VTE risk assessments completed in 48 hours improved from 36.1% to 47.6%. Conclusions Variation in compliance is still evident across the surgical in-patient wards. Going forward, responsibility to complete outstanding VTE risk assessments will be handed to the FY1 on the late shift. Following this intervention, a further audit cycle will be performed, with the aim of 100% compliance in VTE risk assessment completion.

Abstract Background Binge drinking is defined, by 5 or more doses of alcohol on a single occasion (4 or more, in case of women). The excessive alchool consumption is the behavior with the most significant impact on youth mortality and morbidity. Binge drinking is a public health problem that can be preventable. The aim of this investigation was to estimate the prevalence of binge drinking and analyze the associated factors to this behaviour among high school students from Fafe, Portugal. Methods Cross-sectional study. Invited 1334 high-school students, aged between 15 and 19 to fill in an anonymous self-administered digital survey between May and June 2019, wich includes questions about alcohol sociodemographic characteristics, physical activity and smoking. Associations between binge drinking in the last 2 months and the several factors were analyzed through multivariated logistic regression, using IBM SPSS v.20, considering a significance level of 5%. Results A total of 786 students answered the survey (response rate 58.9%), 714 surveys were validated. The median age of participants was 17(1.074 sd) years and 54,8% were girls. The proportion of students from academic high school were 70.9%. Considering all the students estimated binge drinking prevalence was 28.6% (95%IC:25.35-31.79) and 41,5% (95%IC:36.9-45.8) within who have reported to drink. Binge drinking was associated with male gender (OR = 1.75; 95%IC:1.186-2.585), regulary cigarrete smoking (OR = 7.48; 95%IC: 3.422-16.347), being on 12th grade (OR = 2,677; 95%IC:1.625-4.412). There wasńt found association on binge drinking proportion between students from academic or vocational school. Conclusions Our study concluded that binge drinking is common among Fafe high school students. This study provides relevant information to public health authorities about the binge drinke behaviour on this population and makes possible to identify the most high-risk students of binge drinking in order to planning interventions. Key messages Binge drinking pattern is increasing among adolescents and young adults. Future preventive interventions on binge drinking are importante and should consider the associated factors of this behaviour.

Lightning Injury

Background: Lightning injury is a global public health issue. Low and middle-income countries in the tropical and subtropical regions of the world are most affected by lightning. Bangladesh is one of the countries at particular risk, with a high number of devastating lightning injuries in the past years, causing high mortality and morbidity. The exact magnitude of the problem is still unknown and therefore this study investigates the epidemiology of lightning injuries in Bangladesh, using a national representative sample. Methods: A mixed method was used. The study is based on results from a nationwide cross-sectional survey performed in 2003 in twelve randomly selected districts. In the survey, a total of 819,429 respondents from 171,336 households were interviewed using face-to-face interviews. In addition, qualitative information was obtained by reviewing national and international newspaper reports of lightning injuries sustained in Bangladesh between 13 and 15 May 2016. Results: The annual mortality rate was 3.661 (95% CI 0.9313–9.964) per 1,000,000 people. The overall incidence of lightning injury was 19.89/100,000 people. Among the victims, 60.12% (n=98) were males and 39.87% (n=65) were females. Males were particularly vulnerable, with a 1.46 times increased risk compared with females (RR 1.46, 95% CI 1.06–1.99). Rural populations were more vulnerable, with a 8.73 times higher risk, than urban populations (RR 8.73, 95% CI 5.13–14.86). About 43% of injuries occurred between 12 noon and 6 pm. The newspapers reported 81 deaths during 2 days of electric storms in 2016. Lightning has been declared a natural disaster in Bangladesh. Conclusions: The current study indicates that lightning injuries are a public health problem in Bangladesh. The study recommends further investigations to develop interventions to reduce lightning injuries, mortality and related burden in Bangladesh.

Aim: To review the venous thromboembolism (VTE) risk assessment and thromboprophylaxis in the antenatal population in a tertiary health facility in Nigeria and to perform a retrospective VTE risk assessment of the patients with a view of determining those patients that would have needed VTE prophylaxis. Design: It was a retrospective cross-sectional study. Place and Duration of Study: The study was carried out at the University of Port Harcourt Teaching Hospital (UPTH), Port Harcourt, Nigeria from the 1st of February to the 30th of April, 2020. Materials and Methods: The following data were extracted from the hospital notes of 347 consecutive antenatal patients: history/demographic characteristics, risk factors for VTE, thromboprophylaxis, diagnosis and treatment of VTE, using the RCOG guideline 37a of 2015 as a benchmark for comparison. Data was analysed with the aid of a Statistical Package for Social Science (SPSS) software, version 18. Results: VTE risk assessment and thromboprophylaxis  was not a routine practice at the UPTH. Apart from antenatal admission, the most frequent VTE risk factors in pregnancy were  BMI ≥30, Parity ≥ 3, Age > 5 years and current pre-eclampsia at 48.48%, 41.04%, 36.04% and 15.56% of the study population respectively. 131 (37.75%) of the 347 antenatal population fulfilled the criteria for venous thromboprophylaxis with low molecular weight heparin (LMWH) but they were not assessed and the drug was not given. 63 (18.16%) of the study population was to receive LMWH from 28 weeks of pregnancy while 68 (19.60%) of them were to be given from the first trimester. The prevalence of VTE was however very low at 0.02% (1 patient out of the 347 maternities), irrespective of the fact that 41 (11.82%) of the patients had symptoms and signs of VTE. Conclusion: 131 (37.75%) out of the total 347 antenatal patients fulfilled the criteria to be given thromboprophylaxis but the prevalence of VTE was low at 0.02%. It was therefore recommended that a unified Nigerian national guideline should be written.
